    GO ID   Ontology GO Term Definition
    160   Phosphorelay Signal Transduction System  A Conserved Series of Molecular Signals Found in Prokaryotes and Eukaryotes; Involves Autophosphorylation of a Histidine Kinase and the Transfer of the Phosphate Group to an Aspartate That Then Acts As a Phospho Donor to Response Regulator Proteins. 
    155   Phosphorelay Sensor Kinase Activity  Catalysis of the Phosphorylation of a Histidine Residue in Response to Detection of an Extracellular Signal Such As a Chemical Ligand or Change in Environment to Initiate a Change in Cell State or Activity. the Two Component Sensor Is a Histidine Kinase That Autophosphorylates a Histidine Residue in Its Active Site. the Phosphate Is Then Transferred to an Aspartate Residue in a Downstream Response Regulator to Trigger a Response.
